ie, when viewing a "current" period (the current day/week/month/quarter/year),
it will be moved to enclose the current date, if needed, whenever the system date changes.
Previously it would check the modification time and reload only if
it looked newer than the last reload. But this could get confused
somehow by fsnotify events, such that there were unloaded changes
on disk yet pressing g did nothing.
This came up in the context of Docker, but it seems it wasn't possible
for hledger-web to serve remote clients directly (without a proxy)
because of 127.0.0.1 being hardcoded ? Now that can be
changed with --host=IPADDR. The default base url also
uses this address, rather than "localhost" being hardcoded.
Also, the --server flag sounded too close in meaning to --host so
I've renamed it to --serve. The old spelling is still accepted,
at least through the next major release I suppose.
When we don't know a file's format, instead of choosing a subset of
readers based on content sniffing, now we just try them all.
Also, LedgerReader is now used only as a last resort,
as it's not yet competitive with JournalReader.
hledger-lib had a valid install plan with GHC 7.8, but requires GHC 7.10 to compile (currently).
Require base 4.8+ everywhere so that stack/cabal will enforce a supported GHC version early.
Also, bump hledger-ui's "stability" to "stable".
This reader is used by default for files with suffix .ledger or .l,
and tried along with the other readers for files of unknown type.
Currently only the bare minimum of the raw parsed data is used:
transaction dates/descriptions and posting accounts/amounts,
with the rest being ignored.
Amounts are parsed the same way as in the hledger journal format.
Malformed amounts might be ignored instead of error-reported.
